Now with OneLake security, you can define access permissions once, and Fabric will enforce it consistently across all engines. Data owners can create security roles, refine permissions, and control access at the row and column levels to securely share data. For example, you can grant access to only certain folders, tables, or even rows in a lakehouse--restricting Personally Identifiable Information (PII) while keeping other data available. This security propagates automatically, so whether you query the data in SQL or visualize it in a Power BI report, you can only see what has been authorized. With this release, OneLake security will be available for anyone to try without a signup, simply enable the feature directly in your Fabric items.
